hunter wants to add the collapse button to the quick access toolbar. he then wants to organize his toolbar alphabetically for easy access. when he is finished, so not to confuse the next person who uses the program, he has to put the access bar back to the factory settings. below is a screenshot of his options.

which is the correct order of the buttons he would push to complete these actions?

b → c → d
b → d → c
a → d → c
a → c → d
